PUMPING POWER.

SPECIFICATION forming part of Letters Patent N0. 759,574, dated May 10,1904.

A Application filed February 10, 1904. Serial No. 192,999. (No model.)

To nfl/Z whom t T11/Ly cowl/cern:

Be it known that I, EDGAR OTTO WEIDLER, a citizen of the United States,residing at Oil City, in the county of Venango, State of Pennsylvania,have invented certain new and useful Improvements in Pumping Powers; andI hereby declare the following to be a full, clear, and exactdescription of the same, reference beingl had to the accompanyingdrawings, in .to which Figure 1 is a perspective View of a pumping powerembodying my invention. Eig. 2 is an enlarged plan view of the same.Fig. 3 is a side elevation thereof, the power-gear or master-gear beingin section. Eig. 4 is a plan view of the bed-plate or base of thepumping power, showing the split clamp-soeket for the arbor of thepower-gear. Fig. 5 is an end view of the bed-plate looking in thedirection 2O o1c the arrow, Fig. 4. Figs. 6, 7, and 8 are detail viewsof the spindles or arbors of the power-gear and pump-rod wheel and ofthe powereshaft, respectively.

Like symbols reifer to like parts wherever 2 5 they occur.

My invention relates to the construction of that class of devices,commonlyterm ed p umping powers, which are intended for the simultaneousreciprocation of a plurality of rods or equivalent means for actuatingthe pumps of a series or group of surrounding oil or similar wells, andhas for its object the production of a simple, compact, powerful, andrigid machine wherein the coaeting elements are so constructed andrelatively combined as to support the parts against the vi brationincident to the pull and thrust of the load, minimize the wear, and`facilitate repair when required.

Particularly stated, my invention pertains especially to that class ofpumping powers wherein are combined with a bed-plate a hori- Zontalpower-shaft, a power-gear or mastergear revolving on a stub arbor orpintle, and a pump-rod wheel mounted on or carried by the power-gear,and is directed, lirst, to securing rigidity with ready adjustability ofthe arbor of the power-gear, and, secondly, to

facility or' adjustment of the stroke of the pumping-rods. In this classof pumping powers, where the load is carried directly by the power-gearor master-gear and the absence oi' the framing above the power-gearsubjects the step of the arbor to increased strain and vibration, greatrigidity of the arbor, as well as facility of removal i'or repair, isessential, and to secure these requisites I lprovide the bed -plate witha split socket,

which may be east or otherwise formed integral therewith and which isexpanded by a wedge or otherwise and tinished by boring,

so that when the wedge is withdrawn the socket will clamp and uniformlysupport the step ot the arbor against vibration and wear, and such aconstruction and combination in a pumping power embodies one feature ofmy invention.

In connection with a stub-arbor stepped in a clamp-socket, as aforesaid,whereby vibration is eounteracted, I employ a power-gear pro- 7o videdwith a plurality of arborsockets arranged at diii'erent distances fromthe arbor of the power-gear, whereby the position of the pump-rod wheelmay be changed to alter the length of vstroke of the pump-rods, and sucha construction and combinationin a pumping power embodies anotherfeature of my invention.

There are other minor features of invention, all as will hereinaftermore 'fully appear.

I will now proceed to describe my invention more fully, so that othersskilled in the art to which it appertains may apply the same.

In the drawings, l indicates an oblong bed plate, limited as to height,preferably in the 8 5 form of a rectangle, and of such length as willafford room for extended journal-bearings 2 3 for the power-shaft, andin alinenient therewith a socket 4 for the reception of a lixedstub-arbor for the power-gear.

Between the journal-bearings 2 3 is an opening 5 in the bed-plate l toaccommodate the bevel-pinion of the power-shaft, and in the sides of thepillow-blocks or journal-bearings are hand-holes 6 6 for theintroduction and 95 withdrawal oi the nuts 'for the bolts by which thecaps 263a of the journal-bearings are secured. The journal-caps 2 3 maybe cupped and provided with oil ports or passages to facilitatelubrication of the bearings of the power-shaft.

Adjacent to one end of the bed-plate 1 and in alinement with thejournal-bearings 2 3 is a socket 4 for the reception of the fixedstubarbor on which the power-gear or master-gear revolves. This socket 4is in the form of a split cylinder or socket, having a radial slot8,(see Fig. 4,) into which is driven a wedge or equivalent means forexpanding' the socket, and the socket when so expanded is finished byboring in order that when thereafter the stub-arbor for the power-gearor master-gear is inserted and the wedge withdrawn the socket will gripor clamp and rigidly and uniformly support the step or foot of thestubarbor.

9 indicates flanges on the socket 4 adjacent to the radial slot 8,through which pass the clamp-bolts 10. In lieu of or in addition to saidclamping-bolts 10 studs or keys may be.

used in the usual manner to secure the arbor 12 rigidly in the socket 4.l

Surrounding the upper end of the socket 4 and the bearing for the lowere-nd of the powergear hub is the channel or cup 7 for receiving andretaining any lubricant which escapes from the journal oi' thepower-gear or mastergear.

13 indicates the power-shaft, journaled in the bearings 2 3 of thebed-plate 1, which may be provided at one end with a pulley 14 and isprovided between the bearings 2 3 with a bevel-pinion 15, adapted toengage the teeth oil-channel or annular oil-chamber 16, from which aport or passage leads to the journal for purposes of lubrication.

Surrounding the hub of the power-gear 16 and at dijerent distancestherefrom and from the arbor 12 (see Fig. 2) the power-gear 16 isprovided with a plurality of sockets 17 18 19 for the reception of thepintle or arbor 20 of the pump-rod wheel 21, said arbor 2O being changedfrom socket to socket as the length of the stroke of the pump-rods is tobe changed.

The spindle or arbor 2O of the pump-rod wheel is adapted to be removablysecured in either of the sockets 17, 18, or 19 by means oi' a shoulderon the spindle and a nut 20u or otherwise, and the relation of the arbor20 of the pump-rod wheel 21 to the arbor 12 of the power-gear willdetermine the length of the stroke of the pump-rod.

21 indicates the pump-rod disk or pumprod wheel, journaled on the arbor20, carried by the power-gear or master-gear 16, and said disk or wheelis provided at its periphery with a series of holes 22 for the clevis orsimilar swivel connections, whereby the pump-rods are secured to thedisk or wheel 21 when the device is in operation.

The bed-plate, power-shaft, stub-arbor, power-gear, and pump-rod wheelbeing constructed and combined as hereinbefore pointed out, the point ofapplication of the Apower will be so located with relation to the planeof the pump-rods and the plane of the bed-plate that a pumping power ofgreat stability, rigidity, and simplicity is obtained, due largely tothe manner in which the stub-arbor of the power-gear is stepped on thebed-plate and the arbor of the pump-rod wheel is stepped on thepower-gear, whereby facility of adjustment and repair, as well asrigidity of support, is obtained.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is"

1. In a pumping power, the combination with a bed-plate having a splitsocket for the reception of an arbor, of astub-arbor clamped in thesplit socket of the bed-plate, a powergear journaled on the stub-arbor,and a powershaft journaled on the bed-plate for actuating thepower-gear, substantially as and for the purposes specified. v

2. Tn a pumping power, the combination with a bed-plate having a splitsocket for the reception of an arbor, of a stub-arbor clamped in thesplit socket of the bed-plate, a powergear provided with a plurality ofsockets located at different distances from its axis, said power-gearjournaled on the stub-arbor of the bed-plate, a detachable arbor securedin one of the sockets of the power-gear, a pumprod disk or wheeljournaled on the arbor carried by the power-gear, and a power-shaftjournaled on the bed-plate for actuating' the power-gear, substantiallyas and for the purposes specified.

In testimony whereof I aiiix my signature, in presence of two witnesses,this 6th day of February, 1904.
